Light still holds surprises—as demonstrated by researchers from the Ultrafast Phenomena Lab at the Faculty of Physics, University of Warsaw, in collaboration with the Institute of Low Temperature and ...

Ultraviolet (UV) light has higher energy photons than visible light and, thus, has more applications. Researchers have now developed a brilliant innovation -- a solid-state material that can stably ...

Due to their long life and high reliability, visible light emitting diodes (LEDs) are finding their way into more and more applications. LEDs are now found in most automobiles, street lights, outdoor ...

How can we measure visible light? The electromagnetic spectrum includes all forms of light energy, known as electromagnetic radiation. (1) Different types of electromagnetic radiation such as radio ...

(Nanowerk News) High-accuracy spatially and temporally resolved temperature sensing is critical and has broad applications in diverse fields, such as industrial manufacturing, environmental, and ...

Unencased LED lights, however, had a UV intensity of 0. The researchers also recommend that light conditions for the study chambers range from 600–1400 lux of visible light, with UVA radiance at 1–3 ...

Researchers have created a microphone that listens with light instead of sound. Unlike traditional microphones, this visual microphone captures tiny vibrations on the surfaces of objects caused by ...
